how to transform/move around IFCMesh objects

    The following code works for string lines and CadPoints but it won't move an IFCMesh object. The new objects are created but stay at the originals position.

    dp = self.currentProject.CreateDuplicator()
    # create a copy of the selected object
    o_new = wv.Add(clr.GetClrType(o_org.GetType()))
    o_new.CopyBody(self.currentProject.Concordance, self.currentProject.TransactionManager, o_org, dp)                        
    # this is the direction of the alignment at the paste point
    linevec = perpVector3D.Value
    rotation = Vector3D(ps1, ps2).Azimuth - linevec.Azimuth
    #BuildTransformMatrix(Trimble.Vce.Geometry.Point3D fromPnt, Trimble.Vce.Geometry.Point3D toPnt, double rotate, double scaleX, double scaleY, double scaleZ)
    targetmatrix = Matrix4D.BuildTransformMatrix(ps1, p1, rotation, 1.0, 1.0, 1.0)
    o_new.Transform(TransformData(targetmatrix, Matrix4D(Vector3D.Zero)))

    As a test I used the same .Transform on the original, I thought that there may be a "connection" left between old and new, but the old one also stays where it is. .Transform doesn't seem to have any effect on the IFCMesh.

    I found the issue, it was the 


    You can save the result of the transformation into a variable,

    tt = o_new.Transform(TransformData(targetmatrix, Matrix4D(Vector3D.Zero)))

    and that one showed me "UnsupportedUCS".


    tt = o_new.Transform(TransformData(targetmatrix, None))

    it works.
